Application filed March 11. 1907. Serial No. 361.784.

To all whom it may concern:

e it known that CHARLES ll'. Dory, a citizen of the United States, residing at Columbus, in the county of l ranklin and State of Ohio, as invented certain new and useful inprovements in Dump-Cars, of which the owing is a specification.

My invention relates to improvements in dump cars, and has especial reference to the provision of air operated means for dumping and righting said cars.

It contemplates the arrangement of a plurality of air cylinders at convenient points on man mounted upon.

ame construction of a car with the points upon the car bed at ing and righting force is to be or contemplates a link or pitman mounted upon the piston to engage a plate mounted upon the car body to dump same, whereupon said piston will be retracted to its normal position; it further contemplates the provision of a similar link or pitthe piston of a second cylinder which is adapted to posite side of thereon to return position or to right the same; it further eonthe underfr reference to applied; it furt while the air 1piston, and immediately l of the air supply, the piston will drop back into the cylinder out of contact with the car body only contact with the car body,'or preferably will e retracted by means of a coiled spring. Intheaccompanying drawings, which are hereby made a part of this specification, Figure 1 is an end view of a dump car having cylinders mounted upon the underlirame construction to dump and to right the car, the means of holding the car in normal position and. of lifting the side door thereof when dumped being omitted Fig. 2 is a side view of one of the cylinders and the end construction of the car; ig. 3 is an end view of a car provided with my improvements in a dumped position, means for locking the car in. normal osition and unlocking the same being shown; i 4 is avertical section through the piston 110%I between the links; Fig. 5 is a detail of a 1n -Referring to the drawings in which the same numerals indicate the same parts throughout, 1 is the center sill ol the car and 2 is the car body pivotally mounted at 3 upon the supports 4, and adapted to rotate upon said pivotal oints to either side, whereby the car may )e dumped in either direction. The end frame construction of the car is shown in Figs. '1 and 3, in which 5 is the side door, hingedat 6 to the horizontal bar 7 which is pivoted at 8; the arm 9 is pivoted to arm 7 at 10 at its upper end and its lower end i is formed of parallel bars connected at their lower ends 11, and engaging with the rotary lock 12, the lock being held in normal posipivoted lever 13 engagon the rotary lock. arm is lifted out of contact with the lock, the car may be dumped by the application of force thereto on the unlocked side. The construction of the lock and the, means for operating and. controlling the same, form no part of this invention, and need not be described further.

It should be stated however, that if the lock on one side nipulation of the lock on the other side is necessary inasmuch as the depending arm rotates the same readily as said arm passes downwardly, and when the car is restored to its normal position the arm on the lowered side will pass upwardly over the lock until the lower end of said arm contacts with said look, at which instant the arm on the raised side will have been returned to its position of contact with the lock on its side of the car.

The end ol the car body is provided with the plate 15 which is provided at each side with the notches .16 and 17, the latter being ar ranged as here shown upon radii of different lengths.

Appropriately mounted upon the axles of the car is the center sill 1, which extends longitudinally and is the structure of the car body; adjacent t e rear end of the said center'sill secure the strap 19 having the downwardly bent arms 20 and 21, the lower ends of which diverge from the center sill construction, and are supported by means of fillers 22 and 23 in then outstanding position. a

On one side of the center sill upon each of the arms 20 and 21 is mounted a cylinder 26 and 27, the former shown in vertical section,

orally as shown at 30 and having functions to return the piston to its lower position ai3 will position the latter properly for sure contact with the notch 17 or 16.

Referring to Fig. 3, a car in dumped posi tion is shown; the car body 'will be righted by the application'oi air to the cylinder 27, which will drive the pin at the upper end of the link construction thereon in to contact with the notch 16, and the car will thereb be given a sudden impetus upwardly, whic i will cause the same to be righted; In the which need not be described in this applica tion; the piston rod 29 carries a spring 31 which is in contact with the piston 28 at one end and with a shoulder 32 formed on the innor side of theupper end of the cylinder, at its other end, the function of the spring being ter the same has been operated. Pivotally the preferableconstructron however consisting of apair of said links arranged in parallel, and pivoted at their lower ends on the pin 33 and connected at their upper ends by the pin 35. (See Fig. 2.)

construction does not remain in contact with the car body until the latter has reached its normal position, inasmuch asthe initial impetus is sufficient to carry the car back to the normal position. The radius of each of the notches 16 and 17 drawn from the pivot 39 is-of such length that when the'car body is being dumped, notch 17 a will just clear the outer end'of the link construction 34, and will bring notch 16 into proper, position, when the piston rod is the plate 36 which need not be further described in this application; located beneath the plate and mounted upon the links 34 is a projection 37, which, when the links 34 tend to drop inwardl towards the center sill, will act as a stop therefor, and prevent the links from leaving the proper position for contact with the notches '16 and 1 7 mentioned above.

If the air be applied tothe cylinder 26, the piston will be raised, thereby bringing the pin 35 on the links in contact with t e notch l7,on the plate 15; the pressure thereby exerted upon the car body will cause the same to be dumped toward the opposite side, as shown in Fig. 3. It is not necessary that the cross pin 35 on the links 34 remain in contact with the car body until the latter has construction, so that the latter will surely contact therewith when the air is applied to its cylinder.

From the foregoin description it will be the purpose of-givmg the car a swift initial dumping movement which will tendto disparticles of material from the car bottom and sides; this manner of operation the car body is pivotally mounted to .dump at either side, and when the partsare kept in proper condition, the car body will require very slight force to cause the same to therefore I show a short piston rod and consequently a cylinder of short length. :The air isapplied quickly to the piston, and'the contact of the cross pin ,on the links with the plate on the car is sudden and gives the car ody great impetus, so that the latter will continue the dumping movement after the contact'therewith of the link construction has ceased.

The car body must be made strong enough so that the dumping movement may be rather violent, .for the reason that many kinds of material, especially if the same are soft or moist, will not leave the car when it has assume theslanting position'nfor this reason I contemplate a sharp, sudden contact of the link construction with the plate- 15, so that the material in the-car may be given a tendency outwardly away ironrt e car bottom, to assure the complete dumping begin to tilt, and the/swift sudden impetus irn arted by my construction will effectually dis odge material of a sticky or moist composition, whereas a slow, gentle movement .fore be necessary toscrape out the material. My construction'renders all this supplemental labor unnecessary. It isr'urther noted that the link construction does not adhere tothe car, but merely contacts .therewith long enough to give the necessary dumping im etus, whereupon the same is released and t e car completes the dumping movement entirely. disconnected from the linkconstructionprovided. 4 In righting the car it will be, noted that the initial impetus is given .to the car body at the upper notch'in the plate, and on a line withres set to the vertical central plane of the car t at will produce the greatest effect in imparting asuflicient momentum to the car body so that the latter will be carried back to its normal osition without a continuing contact with t e piston rod. Therefore the cylinders and piston rods provided here are When the air is shut off, the spring will retract the piston into the cylinder to its normal position and thelink construction 34 will be returned to proximity to the upper end o the linder; uponits return the lower end of thelinks 34 will engage a lu 38 provided upon the upper external end 0 the cylinder. Lug 38 is positioned so that contact thereby not only econohnzing material, but

performing the desired function in a highly efficient manner. Further by making the connection between the car body and. the piston at all timesmerelv one of impact, so

' that as soon as the air is withdrawn the piston rod drops out of contact with the car I avoid all the accidents possible in a construction in which the piston rod is se cured to the car body during the dumping or righting movement, in case the air should fail to operate properly.
